Measuring the ultraviolet background at from the quasar proximity effect in DESI DR1
Patrick Shaw, Rupert A. C. Croft
Ionizing radiation from quasars reduces the abundance of neutral hydrogen in the surrounding intergalactic medium (IGM), suppressing Ly absorption. This absorption deficit, know…
Large-scale surveys of the quasar proximity effect
Rupert A. C. Croft, Patrick Shaw, Ann-Marsha Alexis +6
The UV radiation from high redshift quasars causes a local deficit in the neutral hydrogen absorption (Lyman-alpha forest) in their spectra, known as the proximity effect. Measurem…
Forecasting the Detection of Lyman-Alpha Forest Weak Lensing from the Dark Energy Spectroscopic Instrument and Other Future Surveys
Patrick Shaw, Rupert A. C. Croft, R. Benton Metcalf
The apparent angular positions of quasars are deflected on the sky by the gravitational field sourced by foreground matter. This weak lensing effect is measurable through the disto…
Weak Lensing the non-Linear Ly-alpha Forest
Patrick Shaw, Rupert A. C. Croft, R. Benton Metcalf
We evaluate the performance of the Lyman- forest weak gravitational lensing estimator of Metcalf et al. on forest data from hydrodynamic simulations and ray-traced simulated len…
Deep Forest: Neural Network reconstruction of intergalactic medium temperature
Runxuan Wang, Rupert A. C. Croft, Patrick Shaw
We explore the use of Deep Learning to infer the temperature of the intergalactic medium from the transmitted flux in the high redshift Lyman-alpha forest. We train Neural Networks…
